Immobilised Glucose Isomerase - 50gPlease note that none of our enzymes are to be considered as being of Food Grade Standard. They are only suitable for use in education.Working Concentration: To be used neatpH range: 6.0 - 9Temperature range: 55 - 70°CSubstrate: 5% GlucoseProduct: FructoseSource: Streptomyces murinusIt's good practice to store enzymes in a refrigerator (5°C approx.). This should give a shelf life of 12 months without significant loss of activity.All enzymes as supplied should be considered as 100% (unless otherwise specified) for example:Cellulase is supplied as 2g powder - 1g in 100ml gives a 1% working solutionPectinase supplied as 100ml - 1ml diluted to 100ml gives a 1% solutionGlossary:pH - Recommended range for maximum activityTemperature - recommended range for maximum activityWorking Concentration - dilution of the Enzyme (as supplied) to this level should give an acceptable reaction time.Substrate - substance to be reacted with the Enzyme and appropriate concentrationProduct - substance produced by breakdown of the substrateSource - origin of the Enzyme
